Arduino USB-MIDI pedals design and code

[ZectionAte]

I posted a simple pedal design on https://www.thingiverse.com/thing:3689641. Free to download, if anyone is interested.
You need an Arduino Leonardo. Code is here: https://pastebin.com/M658ZhEj

I'm definitely not going for real drum pedal feel with this, but they are quite functional.
Uses MIDI-USB output for the kick drum and hi-hat. Much nicer than pressing a button on the controller.
Doesn't interfere with OVR drop if you want to watch youtube at the same time.

May need to set this in Paradiddle options:
MIDI notes are 36 for the kick drum, 42 close hi-hat, 46 open hi-hat.
Can also enable hi-hat pedal sound and adjust the pedal velocity

This is fantastic, thank you so much for sharing it with the community! I'm curious as to how exactly the MIDI messages are received from the app side - does the Arduino show up as a MIDI device under the MIDI menu?

If you'd like to share any videos of it in action, or tutorials etc. on this in the future, I'm sure the community would love to see it (especially on the Discord: https://discord.gg/paradiddle). I'd also be interested in adding a DIY section to the pedal guide at http://paradiddleapp.com/pedal-guide and link to this as well as a couple of other people's DIY pedal projects, if that's okay with you of course.

Once again, thanks for sharing!

No problem.
That's right it appears as Arduino Leonardo in the MIDI menu. Actually, I was pretty surprised it worked:p

The diy section sounds like a good idea. I'll need to practice a lot more before posting any videos though lol.

That's really neat, thank you I just ordered the buttons :)

Nice! btw be careful soldering the buttons: the plastic melts if you leave the soldering iron in contact with the pin for too long. I ruined a couple of them; fortunately it was a pack of 10.

Thank you for the info, I'm printing the pedals atm.

I also printed the case for the Arduino UNO, which I wanted to use. But I had to find out that USB-MIDI isn't supported by the UNO (there is a workaround with flashing the firmware ,though). I think it could be worth to mention it on the thingiverse page. For now I will use a Teensy instead and put the code on github, when it's ready

Thanks for the info on UNO, I have updated the thingiverse page.
